Omg do you even know how long I've had this step??? The answer is 30 years! Yep...It was my mom's and she let me have it. I absolutely love this step and use it for every workout: Step classes, HIIT, grit cardio and even weights! It is awesome and clearly durable since it's 30 years old. It has two levels and you simply pick up the step and take the pieces out from the bottom to make it smaller or taller. My dog also loves it too as she likes to sit on top to watch me work out!!
